rcrossref-defunct

<ul><li><code><a href="/link/cr_citation?package=rcrossref&version=0.3.0" rd-options="" data-mini-rdoc="rcrossref::cr_citation">cr_citation</a></code>: Crossref is trying to sunset their OpenURL API, which
 this function uses. So this function is now removed. See the function<code><a href="/link/cr_cn?package=rcrossref&version=0.3.0" rd-options="" data-mini-rdoc="rcrossref::cr_cn">cr_cn</a></code>,
 which does the same things, but with more functionality, using the new Crossref API.</li></ul>

    (including bibtex, citeproc-json, rdf-xml, etc.), convert DOIs to PMIDs,
    and vice versa, get citations for DOIs, and get links to full text of
